Already have a 3D web app, but need someone to extend it, fix a bug, or add a feature your original team didn't get to? I work inside existing codebases — React, Vue, or vanilla Three.js — to add functionality, fix performance issues, or integrate new capabilities without a full rebuild.

This is common work for me: stepping into an existing 3D viewer or configurator built by another team (or an earlier version of your own product) and extending it. Past examples include adding object selection and multi-unit highlighting to a Vue.js 3D property viewer, mapping dynamic logos onto specific 3D units, and building click/highlight interactions for 3D floor plan visualizations.

Codebase review and scoping before work begins (so you know what's realistic before committing)

Bug fixes, performance optimization, or new feature implementation within your existing 3D web app

Works across React Three Fiber, vanilla Three.js, and Vue.js/Vue Three-based projects

Clear documentation of changes made, so your team isn't left guessing later

Good for: Teams with an existing 3D web product who need focused help — a stuck feature, a performance issue, or an addition the original developer isn't available for.

Pricing: Starting at $75/hour, or a fixed project quote after a short codebase review. Most small feature additions or bug fixes fall in the $300–$800 range; larger integrations are scoped individually.
